Where is the window drain hole located?
3 Answers
The window drain hole is located at the bottom of the door panel. The door drain hole is mainly used to drain water that enters the window gap, such as rainwater or car wash water. Below is relevant information about car drain holes: 1. Concept: The vehicle drain hole is the outlet that discharges accumulated water from the vehicle during rainy days. Generally, vehicle drain holes are located in the following areas: the front windshield of the engine compartment, the four corners inside the sunroof, the lower part of the front and rear doors, inside the fuel tank cap, at the bottom of the spare tire in the trunk, and the gaps between the front and rear headlights and the body fenders. 2. Precautions: There is usually a drain hole below the fuel tank cap. If it gets clogged, water may accumulate in the fuel tank during car washes or rainy weather, potentially damaging the fuel tank. The spare tire in the trunk is generally located at a relatively low part of the body. When driving through water, if the water level rises above the headlights, water may seep in and reach the interior. The drain holes in this area are used less frequently.
Having driven for many years, I'm quite familiar with the locations of window drainage holes. The sunroof's are at the four corners, where rainwater flows down through small holes and drains to the ground near the wheels; the window drainage holes are in the lower edge grooves of the door frames, and you can feel small openings by hand. The positions vary by car model, such as SUVs having their drainage holes near the chassis door frames. Blockages are common, especially in autumn when leaves fall in, causing rainwater to accumulate and leak into the car, damaging the audio system or electrical circuits. Once, I neglected to clean them, and the car's carpet got completely soaked, costing me 800 yuan to repair. Regular checks are simple—just spray with bicycle chain cleaner or use compressed air to blow them out. Don't wait until the rainy season to avoid trouble when you're out. Note the locations in the manual or online diagrams and act promptly to prevent hazards.
Last time my car window leaked, it made me wiser! The drainage hole is located at the corner of the window edge. My car is a hatchback, and the sunroof drainage holes are at the four corners above the windshield; the window ones are at the bottom groove of the door frame, easily reachable. Dust can easily clog them, so I use a thin wire to unclog them. Don’t misjudge the location—some are hidden deeper. If rainwater can’t drain, the interior can mold and cause electrical shorts. Pro tip: Check weekly, and if unsure about the location, ask at a repair shop. DIY is easy—keep them clear for safe driving. As a young car owner, sharing this experience saves hassle and money.
